Teaching Method
Outline:
When an external load is applied to a machine or structure, whether or not those members or the entire structure can withstand the load is determined by the force (stress) and deformation (strain) generated in the member. The goal of this subject is to understand the concepts of stress and strain, and to learn how to analyze the relationship between them and loads, as well as how to apply the analysis results to mechanical design.
Style:
Lecture time will be used to teach how to analyze problems in mechanics of materials. We want you to deepen your understanding of learning by solving the practice problems specified as appropriate. Do your best to prepare for the quizzes and midterm exams (held multiple times to diversify risk) that will be held in supplementary classes.
*Since this subject is an academic credit subject, practice assignments will be given every four hours of each lecture as post-study study. [31 hours of class time + 60 hours of self-study time]
Notice:
In order to understand the lecture content and be able to apply it to mechanical design, it is necessary to acquire the "techniques" to perform accurate analysis, and I would like you to be sure to carry out independent exercises after the lecture. It is also important not to make mistakes in calculations that involve a mix of large and small numbers and in unit conversions. This is an important exam subject for employment and further education, so I hope you will do your best to get a high score on the actual exam.
